    How to protect plaster step from Kreepy Krauly

    Today I noticed that the frequent bumping of the Legend against the first step has worn down the step corner for several feet. It tends to stay there with the body (between the tires) pressed against the step until the water pressure backs off. So far, my thought about preventing further...

    Cannot lower TA to 100 after aeration

    I had been running the pump all day to aerate and get it over with, and tested the water twice a day at first, then once a day after discovering the rate of increase. I replaced my jets with these fountains to create bubbles on the surface. They definitely raised pH, though perhaps not as fast...

    Cannot lower TA to 100 after aeration

    I find this hard to believe, but one day after switching back to acid for one application, I have gotten TA to around 100-110. After two weeks of being stuck around 130 while using all that powder, I finally feel a great deal of relief that this is over. I wonder if I am the only person to...

    Cannot lower TA to 100 after aeration

    Fortunately, after adding all that powder, there is no sulphur odor. I need to go to HD--I see they carry muriatic acid. Frankly, I was a bit put off by the hazard and fumes, especially off just a small breeze, but I think I will try that again. To Richard's point about aeration, I have...

    Cannot lower TA to 100 after aeration

    Thanks Jason. True about the TA strip measurement not being correct. As I mentioned in the other reply, I don't believe the level was low enough to trigger the autofill. Rain did not appear to elevate the TA in any noticeable way, but there definitely won't be any more autofilling since it is...

    My TA for the last week at 140

    Re: Cannot lower TA to 100 after aeration This is the reason why I've been trying to lower TA. When it was higher, the pH clearly drifted back up after adding acid before I started to aerate. What I don't know is whether 130 is a level that will keep the pH stable and in range, since the...

    Cannot lower TA to 100 after aeration

    Yes, there is an autofill, but it was not active. It did just rain on May 8, 9, and 12. 4" in fact on the 12th. Less than 1" the prior week. But the TA seemed stable even before it rained for about a week. Your suggestion about acid is interesting. Is it a known issue that powder is not...

    Cannot lower TA to 100 after aeration

    My TA was high in April--around 200. From reading the aeration instructions here, I've been adding muratic acid first, then sodium bisulfate, since 4/27 I believe. By May 1, my TA readings were averaging around 130. Since then, I have still been aerating 20-24 hours a day and have added...
